How quickly can a pluck reach a spider?
Fit the specimen and set conditions before running.
A connected taut radial strand carries a vibration toward the hub. Tension raises the ideal wave speed; greater mass per unit length lowers it.
One taut radial string: c=√(T/µ), length 0.2 m. Web branching, nonlinear silk stiffness and damping omitted; no species strength claim.
Send a vibration to the hub in less than 5 ms over a 20 cm strand.
Send a vibration along taut silk to the hub.
